I never bother to strive for 100% completion as it usually involves doing stuff I find completely and utterly dull. The closest I've ever come was 98% on GTA: Vice City. I never could do the target practise at the gun shop in order to get it to 100%.
I would love to complete Future Perfect enough to unlock all the characters. Just to see what little statements they would say when you chose them in multiplayer. Doing it was far to hard for me though.Kungfu_Teddybear said:Only game I have ever completed 100% was Timesplitters Future Perfect. Then 2 days later the save file corrupted and I did it all over again.
